Since the file is very big and my local nor udacity cloud did not open it fluently, I have taken sample of 10000 rows randomly. then I did save it and work with this sampled dataset locally. I have commented out all the steps that are taken but not needed for clarification of what has been done.
To load the datasets of the dictionary of titles and the whole dataset:
# import all packages and set plots to be embedded inline
import numpy as np
import pandas as pd
import matplotlib.pyplot as plt
import seaborn as sb
pd.set_option('display.max_columns', None)
pd.set_option('display.max_colwidth', None)
%matplotlib inline
# import chardet
# # Detect the encoding of the file
# with open('pisa2012.csv', 'rb') as rawdata:
# result = chardet.detect(rawdata.read(10000))
# # Read the CSV file using the detected encoding
# df = pd.read_csv('pisa2012.csv', encoding='latin-1')
# #As Dataframe is really big and difficult to handle on jupyter, I take random samples.
# dfsampled = pd.DataFrame()
# dfsampled = df.sample(n=1000, random_state=42)
# dfsampled.to_csv('dfsamplednew.csv',index=False)
dfdict = pd.read_csv('pisadict2012.csv', encoding = 'latin-1')
dfsampled = pd.read_csv('dfsamplednew.csv')
dfsampled.head(2)

Now, since the column naming is not easy to comprehend, I will rename them according to the titles given in the dfdict.
# Rename the columns and set the codes as key:
dfchangeddic = dfdict.rename(columns={'Unnamed: 0': 'code', 'x': 'title'})
# Convert it to dictionary:
dic = dfchangeddic.set_index('code')['title'].to_dict()
#Rename the database column names:

Actual Dataset is (485490,636), I have taken a smaple from it which has 10000 rows × 636 columns.
I'm most interested in figuring out how geography is relatable to predicting the distribution of succesful students.
I expect that student's origin and hardwork will have the strongest effect on students first round pass in the exams: the more dediacted the student personally, the higher the chance. I also think that the other environmental factors: from family and school environment, will have effects on the success, though to a much smaller degree than the main effect of hardworking.
I'll start by looking at the distribution of the main variable of interest: student final weight in place of scores, and Country that tests have been done.
# Create boxplot
plt.boxplot(x= prepared['FINAL STUDENT WEIGHT'])
# Label axes
plt.xlabel('Grade')
plt.ylabel('Value')
# Show plot
plt.show()
There is clearly an outlier, to visualize deeper level of which grades are mostly achieved, here is a way to do it:
prepared[prepared['FINAL STUDENT WEIGHT'] >= 1000]

There are 66 different countries and provinces that PISA test is done.
#plot how is the scoring distribution of students:
plt.figure(figsize=[8, 5])
plt.hist(data = grade_gone, x = 'FINAL STUDENT WEIGHT')
plt.xlabel('Students Grade')
plt.show()
# there's a long tail in the distribution, so let's put it on a log scale instead
log_binsize = 0.025

plt.figure(figsize=[8, 5])
plt.hist(data = grade_gone, x = 'FINAL STUDENT WEIGHT', bins = bins)
plt.xscale('log')
plt.xticks([1e2,1.5e2, 2e2, 3e2, 4e2, 6e2, 1e3, 2e3],['100','150','200','300', '400', '600', '1000', '2000'])

The plot displaying PISA test scores reveals a unique logarithmic decline from 100 to 2000, with distinctive features including twin peaks at 130 and 200, a slight incline between 400-1000, and a sharp drop just before 400. These patterns highlight significant variations in educational performance among participating countries and regions. Further investigation is needed to understand the factors driving these trends, their policy implications, and how to address disparities and improve global educational outcomes effectively.
Next is to Visualize how is participant countries expressed:
# Returns the sum of all not-null values in column
country_sum = grade_gone['National Centre 6-digit Code'].value_counts().sum()
# By default, returns the decreasing order of the frequency.
country_count = grade_gone['National Centre 6-digit Code'].value_counts()
## Return the highest frequency in the column
max_type_count = country_count[0]
total_records = len(grade_gone['National Centre 6-digit Code'])
country_ratio = country_count/total_records
country_order = country_count.index
## Return the maximum proportion, or in other words,
## compute the length of the longest bar in terms of the proportion
prop = max_type_count / country_sum
# Specify the figure size in inches, for both X, and Y axes
plt.figure(figsize =[4,10])
sb.countplot(grade_gone, y = 'National Centre 6-digit Code', color = 'blue', order = country_order)
plt.xlabel('Number of Records')
plt.ylabel('Contries')
plt.xlabel('Proportions');
plt.title('Proportion of Records per Country')
plt.show()
The plotted bar chart, which reflects proportions rather than raw counts, offers a captivating perspective on the geographic distribution of contributors in the dataset. Predominantly, Mexico, Italy, Canada, and Brazil emerge as the top contributing nations, collectively representing a significant chunk of students. Given this, it's pivotal to approach the data cognizant of the fact that outcomes and trends may be disproportionately influenced by students from these countries, which might introduce a geographic bias.
As most of the frequent countries are among (OECD Countries), let us see if this proved by a pie chart:
# Use the same dataset
sorted_counts = grade_gone['OECD country'].value_counts()
plt.pie(sorted_counts, labels = sorted_counts.index, startangle = 90, counterclock = False);
plt.title("Proportion of OECD Countries among Dataset's Countries")
plt.axis('square');
It is clear from the pie chart most of my data is from OCED countries.
Now Next to see students spendture time:
# let's plot all three together to get an idea of each ordinal variable's distribution.
fig, ax = plt.subplots(nrows=3, figsize = [12,12])
default_color = sb.color_palette()[0]
sb.histplot(data = grade_gone, x = 'Out-of-School Study Time - Homework', color = default_color, ax = ax[0])
sb.histplot(data = grade_gone, x = 'Out-of-School Study Time - With Parent', color = default_color, ax = ax[1])
sb.histplot(data = grade_gone, x = 'Out-of-School Study Time - Computer', color = default_color, ax = ax[2])
plt.ylabel('counts')
plt.show()
plt.show()
The data from the histograms shows students spend more time in terms of hours on homework than spending time with family and outside school explorations.
I'll now look at the other features in the data to see if any of them hold interesting properties.
# let's start with the major dimensions
fig = plt.subplots(figsize = [8,4])
variables = ['No of ALL <class period> a week']
for i in range(len(variables)):
var = variables[i]
plt.hist(data = grade_gone, x = var)
plt.xlabel('{}'.format(var))
plt.show()
outliers_gone = grade_gone[grade_gone['No of ALL <class period> a week'] <= 100]
In the data, the majority of students typically undergo between 30 to 40 hours of classes weekly. However, there are some notable outliers, especially among students from Singapore. Some Singaporean students report an exceptionally high number of class hours, reaching up to 100 hours a week. This extreme value is significantly above the typical range and suggests either an incredibly intensive study regimen or a possible data recording discrepancy.
Now further evaluating possible contributing factors:
# let's start with the major school wise facts that may contribute, student-teacher relation, any Tuancy in respect of time and type, number of classes in hours, and grade repition.
fig, ax = plt.subplots(nrows=6, figsize=[8, 14])
variables = ['Student-Teacher Relation - Get Along with Teachers',
'Grade Repetition',
'Truancy - Late for School',
'Truancy - Skip whole school day',
'Truancy - Skip classes within school day',
'No of ALL <class period> a week']
for i, var in enumerate(variables):
ax[i].bar(x=outliers_gone[var].value_counts().index,
height=outliers_gone[var].value_counts().values)
ax[i].set_xlabel('{}'.format(var))
ax[i].set_title(var)
plt.tight_layout()
plt.show();
School-wise factors play a significant role in understanding students' academic experience. A paramount factor is the student-teacher relation, where the majority of students conveyed that they have a good relationship with their teachers. A smaller yet notable proportion of students strongly agree with this sentiment, suggesting an exceptionally positive bond. However, there's also a minority that disagrees, pointing towards areas where school dynamics could be improved.
Regarding truancy, both its frequency and type provide insights. Most students adhere to their schedules and are punctual, emphasizing a general commitment to their educational responsibilities. If any classes are skipped, it's usually limited to one hour or less, which suggests that while occasional distractions or challenges might arise, they do not typically result in extended absences.
Lastly, the data on grade repetition highlights a positive academic trend: the vast majority of students don't find themselves needing to repeat a grade. This can be indicative of efficient teaching methods, students' dedication, or a combination of both, leading to a successful academic progression.
Next is to look over what factors outside school can have effect:
# let's start with the major schoolwise facts that may contribute, student-teacher relation, any Tuancy in respect of time and type, number of classes in hours, and grade repition.
fig, ax = plt.subplots(nrows=5, figsize=[12, 16])
variables = ['Mother<Highest Schooling>',
'Father<Highest Schooling>',
'Gender',
'ISCED level',
'Attend <ISCED 0>']
for i, var in enumerate(variables):
ax[i].bar(x=outliers_gone[var].value_counts().index,
height=outliers_gone[var].value_counts().values)
ax[i].set_xlabel('{} '.format(var))
ax[i].set_title(var)
plt.tight_layout()

Upon examining the student sample, a few defining characteristics emerge. First and foremost, when considering parental education as gauged by the ISCED levels, both parents of most students are observed to have attained an average education level of 3. This suggests a uniformity in the educational background of the parents, which may have implications on the students' home learning environment and academic support.
The gender distribution of the students is almost evenly split, but with a slight preponderance of females. This subtle skew might have implications in classroom dynamics, teaching methodologies, or even peer interactions, depending on the broader cultural and school-specific contexts.
Furthermore, a dominant proportion of these students has been enrolled in the ISCED test for a duration surpassing a year. This prolonged engagement indicates that most students in this sample have had sufficient time to familiarize themselves with the ISCED system, its requirements, and its evaluative measures. Such familiarity might play a role in their academic preparedness and overall performance.
The variable of interest here appears to be the International Grade, which shows a concentrated distribution with most students scoring between grades 9 and 10. When considering the geographic distribution, this high achievement pattern could be influenced by the prominent contribution of students from countries like Italy, Mexico, Spain, and Switzerland. It would be worthwhile to examine if students from these countries have a particular propensity to score in the higher grade bracket, potentially skewing the overall results. Unusual points in the data are the limited counts for lower International Grades, notably grade 7, and the disproportionately high number of students from specific countries.
Unusual distributions would be the stark contrast between the high counts for grades 9 and 10 versus the lower grades, and the high representation of certain countries over others. This may necessitate a more in-depth investigation to ascertain the reasons behind such disparities and distributions, ensuring they don't unintentionally bias any conclusions drawn from the dataset.
In this section, investigate relationships between pairs of variables in your data. Make sure the variables that you cover here have been introduced in some fashion in the previous section (univariate exploration).

To start off with, I want to look at the pairwise correlations present between features in the data.

They don't have strong correlations with any other numeric variables in the dataset, but it shows a weak positive relation of time spendture of students spending with their parents and computer, and that spending time on homework is weakly positive with the total number of class periods in school.
Now I look for any relations among categorical features.

Firstly, it's evident that the highest-scoring students come from Indonesia and the USA, despite Italy having more participants in the sample. This might indicate the quality of education in these countries. Another noteworthy finding is that non-OECD countries tend to have students with higher average scores compared to OECD countries. Additionally, males scored slightly higher, which could be attributed to diligence in their studies although females tend to spend more time on homeworks. As the educational levels of students' mothers and fathers did not seem to correlate with higher scores. In fact, students with parents at level 1 or lower education achieved higher scores than their peers, while students with parents of higher educational levels tend to spend more time on studying. The data also reveals that students who spend more time on homework which are mainly in the USA and Singapore, tend to come from non-OECD countries, have good relationships with their teachers, experience minimal class truancies, and have parents with education levels of 2 and 3. On the other hand, students who spend more time on computers are predominantly from Kazakhstan, Russia, and Bulgaria, with lower representation in Indonesia and the USA. These students also tend to have good relationships with their teachers, parents at education levels 2 and 3, and minimal truancy, usually skipping no more than two classes or a day of school. Lastly, students with the highest number of classes per week are typically found in Singapore and Costa Rica. These students are often from non-OECD backgrounds, report dissatisfaction with their teacher-student relationships, have parents with lower education levels, and exhibit moderate rates of class and school-day truancy. Students from kazakhestan and Tunisia spend by far the most time with parents averaging around 1 to 2 hours daily. While other countries spend less than 1 hour on average with parents, spend on average 2 3 hours on computer, and all countries spend on average 5 hours on homework outside school daily peaking in China, Russia and Singapore for around 15 hours daily.
The data graph presents several intriguing observations.
I create some plots of multivariate, to explore further into the relations. Here's the first multivariate plot:
# 1. Country vs. Average Student Weight with Gender as a Hue
plt.figure(figsize=(15, 8))
sb.barplot(data=clone3, x='National Centre 6-digit Code', y='FINAL STUDENT WEIGHT', hue='Gender', ci=None)
plt.xticks(rotation=90)
plt.title("Country vs. Average Student Weight by Gender")
plt.tight_layout()
plt.show()
/var/folders/_c/fpzkxkgx7kz539gs00mzdv900000gn/T/ipykernel_3804/1059267278.py:3: FutureWarning: The `ci` parameter is deprecated. Use `errorbar=None` for the same effect. sb.barplot(data=clone3, x='National Centre 6-digit Code', y='FINAL STUDENT WEIGHT', hue='Gender', ci=None)
This bar chart represents the average student weight for each country, separated by gender. It is in the highest scoring countries that males score slightly higher than females. The variation in student weights across countries is evident, and within many countries, there are discernible differences between the average weights of male and female students.
Next, we'll plot "Country vs. Average Student Weight" with "Time on Computer" as a size parameter.
# 2. Country vs. Average Student Weight with Time on Computer as a Size Parameter
plt.figure(figsize=(15, 8))
sb.scatterplot(data=clone3, x='National Centre 6-digit Code', y='FINAL STUDENT WEIGHT',
size='Out-of-School Study Time - Computer', sizes=(10, 200), hue='Out-of-School Study Time - Computer', palette='Reds')
plt.xticks(rotation=90)
plt.title("Country vs. Average Student Weight by Time on Computer")
plt.tight_layout()
plt.legend(loc='upper left', bbox_to_anchor=(1, 1))
plt.show()
This scatterplot illustrates the average student weight for each country, with the size of each point representing the average time students spend on the computer. The color gradient (from light to dark) also represents the amount of time spent on the computer. Larger and darker points suggest that students in those countries, on average, spend more time on the computer.
Next, I'll plot "Country vs. Average Student Weight" with "Time on Homework" as a size parameter.
# 3. Country vs. Average Student Weight with Time on Homework as a Size Parameter
plt.figure(figsize=(15, 8))
sb.scatterplot(data=clone3, x='National Centre 6-digit Code', y='FINAL STUDENT WEIGHT',
size='Out-of-School Study Time - Homework', sizes=(1, 200), hue='Out-of-School Study Time - Homework', palette='Reds')
plt.xticks(rotation=90)
plt.title("Country vs. Average Student Weight by Time on Homework")
plt.tight_layout()
plt.legend(loc='upper left', bbox_to_anchor=(1, 1))
plt.show()
This scatterplot represents the average student weight for each country, with the size of each point indicating the average time students spend on homework. The color gradient (from light to dark) also symbolizes the amount of time spent on homework. Larger and darker points suggest that students in those countries, on average, spend more time on homework. As from the data, students from US who spend lots of time on homework get high scores, while students in Indonesia with less spendture time on studying get as nearly same scores of US students. The same goes for other countries whom students try hard on studies yet there are schools and studentds who dont spend that much of time to get the same result. As far as it goes it is clear from the plots that spending time on computer and socializing with parents could not express a significant relation, from now on I look further into homework time spendture. As well as I will use one parental educational level as it aligns with the mother education level.
Next, I'll visualize "Country vs. Average Student Weight" with "Time with Parents" as a size parameter.

What this Multivariate plot can clearly show is that students of US and Indonesia score higher as they have parents of higher levels and a moderate ratio of Skipping classes, what is interesting is not necessriliy they have a very good relation with their teachers like other countries, of Mexico, Italy which is due to the count of the sample I have taken.
Now, I want to look for how is features distribued among US and Indonesian students

Looking further in the Indonesean distribution it is that not specifically students who have study more time score higher, instead students who have good relation with teachers and if they are of parents of higher education cscore higher.

While students of US behave differently, they have more truancies and higher parental education leve, what is the same with the indoneasean education is that students who study harder does not nessecerily score higher, and as students get along better with teachers their probability of getting higher scores is more.

Yes, there were several intriguing interactions observed. The behavior of students from the US stood out. Despite having higher truancy rates and higher parental education levels, their performance trend mirrored Indonesian students. Specifically, dedicating more time to studies did not necessarily guarantee higher scores. Moreover, while one might expect a direct correlation between study time and academic performance, the data revealed that the strength of the student-teacher relationship was a more influential factor in both the US and Indonesian contexts.
A prominent relationship observed was the influence of parental education levels on student performance. Both US and Indonesian students, who had parents with higher educational qualifications, tended to score better. This relationship seemed to be strengthened when combined with a moderate ratio of skipping classes, indicating that occasional truancy did not significantly deter academic performance. Interestingly, while one would assume that a strong student-teacher bond, and students longer study time would be universal among high scorers, the data revealed that students from countries like Mexico and Italy, who had excellent relationships with their teachers, did not necessarily outperform their peers. This observation might be attributed to the specific sample size and selection taken for this investigation.
The investigation into the PISA 2012 dataset, specifically focusing on student behaviors, parental influence, and academic performance, has unveiled several multifaceted insights:
Study Time vs. Performance: Contrary to traditional beliefs, more hours spent studying does not necessarily guarantee better academic performance. Both US and Indonesian students exemplified this, where sheer study hours were overshadowed by factors like student-teacher relationships and parental education levels.
Parental Influence: The educational background of parents, especially in non-OECD countries, revealed surprising patterns. Students with parents holding Level 1 or even lower educational credentials outperformed their peers, challenging the conventional notion that higher parental education always benefits children's academic performance.
Digital Influence: The data showed diverse patterns of computer usage across countries. While students in Kazakhstan, Russia, and Bulgaria predominantly spend more time on computers, this trend is less evident in countries like Indonesia and the USA.
Gender Dynamics: An intriguing observation was the slight edge male students had in performance, even though females, on average, dedicated more time to homework.
Teacher-Student Relationship: The bond between students and teachers emerged as a potent predictor of academic performance. Countries where students reported a stronger bond with their teachers saw better overall scores. However, this wasn't a universal trend, as seen with countries like Mexico and Italy.
Country-wise Analysis: The sample representation emphasized the disparities in academic performance across countries. While countries like the USA and Indonesia boasted higher scores, nations like Mexico and Italy, despite having good student-teacher relationships, didn't necessarily reflect the same success.
A comprehensive view of the data suggests that academic success isn't the outcome of a single factor. Instead, it's the interplay of multiple elements – from parental education, student-teacher relationships, truancy rates, to personal diligence in studies.Most students, irrespective of their country, had a favorable relationship with their teachers and exhibited commitment to their academic responsibilities. The data also showed that most students had been engaged with the ISCED system for over a year, hinting at their familiarity and preparedness with the system.
Given these findings, future research could delve deeper into understanding the nuances behind these patterns, especially the role of cultural and socio-economic factors. For instance, why do students with parents of lower educational levels in non-OECD countries perform better? Or, how can schools globally foster stronger student-teacher bonds to enhance academic outcomes?
In conclusion, this investigation underscores the complexity of academic performance and its influencing factors. It's not a linear equation but a matrix of intertwined elements that together shape a student's academic journey.
